Description
When running the socks server as a systemd unit, and increasing the soft limit of the number of open files in the systemd unit file to 500000, I periodically get the service crashing because the microsocks program terminates with a
*** buffer overflow detected ***: terminated
I increased the file limit in order to accomadate more connections simultaneously, but now I am running into this problem. Is it a bug?

Research direction
Start by reproducing the microsocks crash as a systemd service with the open-file soft limit set to 500000 and enough simultaneous connections to trigger the failure. Inspect the resulting buffer-overflow report and relevant connection-handling paths; done means identifying and fixing the overflow and confirming the service remains stable under the higher limit.
